RE: Would the HP-15C Limited Edition Firmware Age Away?
Quote:I've checked the Atmel technical documentation about the SAM7L128 and SAM4LC4 microcontrollers that (I think) are used in the HP12/15 Platinum/LE. The minimum guaranteed data retention time for the Flash memory inside these chips is of 10 years in the SAM7L128 and 15 years in the SAM4LC4.

I wonder if a much longer time could be expected. My HP-15C is already over 6 years old. If it only has an expected lifetime of 4 more years, I will be sad.
